STORAGE PLANT.

To all whom it may concern:

Be it known that I, ERNST MEIER, a subject of the King of Prussia, residing at 12 Akazienstrasse, Scheneberg, near Berlin, Germany, have invented certain new and useful Improvements in Storage Plants; and I do hereby declare the following to be a full, clear, and exact description of the invention.

The present invention relates to a storage plant having an arched or flat bottom or floor which is supported by pillars and which is provided with discharge openings.

The invention consists substantially in the edges of said discharge openings in the floor being directly supported by the pillars.

In order that the invention may be clearly understood reference is made to the accompanying drawings in which several embodiments are represented by way of example, and in which:

Figure 1 is a vertical section through an arch as well. as through two pillars of the floor of the storage plant; Fig. 2 is a vertical sectionon the line 34 in Fig. 1; Fig. 3 is a horizontal section on the line 56 in Fig. 1; Fig. 4 is a section on the line l2 in Fig. 1; Fig. 5 is a plan of a discharge opening; Fig. 6 is a vertical section through another form of storage plant; Fig. 7 is a section on the line 78 in Fig. 6; Figs. 8 and 9 are sections similar to Figs. 6 and 7 and show the shutting device on an enlarged scale.

The floor of the store house or magazine consists of vaults or arches c (Fig. I) which are supported by arch-piers or pillars a and binding arches 1) between the latter. In the plant represented in the drawing, the pillars a have an I-shaped cross-section, so that they have a web a and two flanges a Immediately over each pillar a there is an opening cl in the floor or bottom which is used for drawing off the material, such as coal, grain and so on, which is on the floor. This opening (Z is made in such a manner that the edge of the same is supported directly by the flanges a of the pillars. Under each discharge opening of there is provided a slide-way or chuted which is supported by the web a of the pillar, with which it may be integral as shown. In the plant represented this chute (1 together with the flanges a of the pillars forms a funnelshaped channel (1 through which the material coming from the opening (1 can be conveyed laterally into a wagon or the like. This channel may be closed at the side opening by a grating which consists of planks, beams or iron bars e. The planks are preferably arranged at right angles to the direction of the pressure of the material which is to be-discharged, and rest on supporting brackets or arms f. which are built into the flanges a of the pillars. When the material is to be withdrawn from an opening d, the planks e are knocked down from the arms f so that the material Specification of Letters Patent.

can escape through the opening d and the lateral opening 9 of the channel g.

In the form according to Figs. 6 to 9 angle irons h are built into the pillars (1 below each discharge opening d, and flat bars 1' are revolubly suspended from them by means of pivots h. Also angle irons 7c are built into the pillars a, said angle irons being provided with a hole is (Fig. 9). There are corresponding holes i" provided at the lower end of the bars i. Pins Z are inserted through the holes *5 in order to fasten the bars 1' to the angle irons 7c. Brackets 11 on which trough-shaped U-irons m lie loosely, are arranged on the bars i. These U-irons are arranged in the iorm of a grid or grating, similarly to the planks 0 according to Fig. 1, and usually close the lateral discharge opening 9 of the channel q which is formed by the chute d and the flanges a of the pillars.

When the material is to be drawn off, it is only necessary to pull the pins Z from the holes is, i. In this case the frame which consists of the bars i and the U- irons m is swung up by the pressure of the mass which is to be discharged, and the U-irons m slide off from the brackets i When all the material has passed through the openings (Z and g, the U-irons m are again placed on the brackets i and the bars are connected with the angle irons k by means of the pins Z.

In case it is desired to withdraw only a part of the material through the openings cl and g, an additional transportable auxiliary hopper n (Fig. 6) is used. This auxiliary hopper n is provided with a sloping plate 72/ (Fig. 6) and two side plates WP, and is generally closed at its lower end by a curved slide 0 to which a handle 0 is attached. The slide 0 is provided with sectorshaped side plates 0 which are revoluble on pivots n on the sides n of the hopper. The hopper n is arranged on a frame 19 which rests on wheels 19. Pins n are attached to the sides a of the hopper, with which pins hooks 0 can engage, said hooks being arranged pivotally on the floor 0.

When the material is to be partially emptied from a discharge opening (I the auxiliary hopper n is moved in front of the lateral opening 9 of the channel q which is situated under said opening d, and the hooks c are placed over the pins n". The pins Z (Fig. 9) are then pulled out of the holes 70, i. Consequently the bars i are swung forward somewhat, by the pressure which is exercised by the material on the Uirons m, until the latter are situated at the edge of the sides n of the hopper. The U-irons are then driven sidewise singly by a hammer or the like until they are released from the edge of the one side n of the hopper. As soon as they are released from this side they are sent into this hopper n by the material which flows into the same.

When all the U-irons m have been removed from the opening g in the manner described, the material is withdrawn as desired by opening the slide 0. If the withdrawal of said material is to be interrupted, the slide 0 is shut, and the bars 11 are again secured by inserting the pins Z through the holes 70, 'i (Fig. 9). The U-irons m are then placed on the brackets '6 again in the following manner. A workman goes to the material which is in the hopper n and in the first place slopes or shovels away so much of the material which is in the hopper n near the upper end of the opening g that the uppermost U-iron m can be placed on the respective brackets F. This uppermost U-iron m may be put in place by the same being first pushed out sidewise from the inside of the hopper n behind the one bar 1' and then sidewise behind the other bar t'. When the uppermost U-iron m is placed on the respective brackets 1?, the material which is in the hopper n is then sloped off still more in order to be able to place the second uppermost U-iron m 011 the respective brackets i and in this manner the material in the hopper n is sloped off step by step until all the U-irons are again placed on the brackets F. In accordance with Fig. 6 the material in the hopper n has been sloped off so much that the third U-iron-m from the top can be placed in position. When all the U- irons are again placed on the brackets '5 the auxiliary hopper n can be removed again after the hooks 0 have been released.

The auxiliary hopper a may also be employed with the closing device e f represented in Fig. 1.

' Instead of the I-shaped cross-section represented in the drawing, the pillars may have a square, U-shaped or other cross-section. Also instead of single pillars, groups of several pillars may be provided, for example four props or columns standing at the corners of a quadrangle, between Which the discharge openings are arranged.

The bays may also rest on iron girders supported by the pillars instead of on binding arches.

Masonry, concrete, beton with iron embedded therein may be used as building material for the plant.
